The South Australian Opposition says it is time for the State Government to tell taxpayers how much it paid Lance Armstrong and his related companies for his Tour Down Under appearances.

Armstrong is likely to be stripped of his Tour de France titles because he has decided against contesting doping allegations.

He made three visits to Adelaide to be part of the Town Down Under.

SA Opposition finance spokesman Rob Lucas says in light of the doping scandal, South Australians deserved to know how much Armstrong was paid.

"The position of the government from Mike Rann through to Jay Weatherill has essentially been these are commercially-confidential and it might ruin our future negotiations if we say how much has been given," Mr Lucas said.

"Well I think those arguments are now blown out of the water.

"You won't be negotiating with Lance Armstrong or anyone like that in the future, so public interest I think now outweighs any other claim."

SA Health Minister John Hill said he personally believed the Livestrong Cancer Research Centre in Adelaide should distance itself from Lance Armstrong.

The research wing of the Flinders Centre for Innovation in Cancer is named after Armstrong's Livestrong Foundation.

Mr Hill said it would be a decision for the board.

"I don't think he should be glorified in whatever way in future, so that's my personal view," he said.

"I guess it's up to the Flinders foundation how they deal with those issues, but they do want to keep an association with the charity that is doing very good work."

Not tarnished

Chairman of the Flinders Medical Centre Foundation Alan Young said the work of its cancer research centre would not be tarnished by the doping controversy.

He said no money had been exchanged between the parties and the centre's focus on cancer prevention and treatment would continue.

"Lance's riding career is Lance's riding career and I'm aware of the controversy and it's disappointing and sad that a process like this is happening," he said.

"But nevertheless it doesn't detract for one minute from the good work that's being done by us as two charities, that's Livestrong and the Flinders Medical Centre Foundation.

"We're not in the business of making judgments about people's other activities, particularly in this case someone else's professional activity. We leave that to people who are better-placed than us, but what I can say is that the value that we've got out of the connection through Livestrong and as far as I'm aware they're the number one survivor program in the world and there's a lot to be learnt from them."

On another doping matter, the race director of the Tour Down Under, Mike Turtur, said he would be more public these days if there were a positive drug test result.

Race organisers are being accused of a cover-up over stage-winning Italian cyclist Giampaolo Caruso being stripped of his win nine years ago.

Turtur said he followed protocol by notifying the international cycling body of the positive drug test and it posted the breach on its website.

He conceded he would act differently if the breach were detected today.

On the Armstrong scandal, Turtur said he did not think the Tour Down Under brand would suffer any permanent damage.

"Our race is bigger than Lance Armstrong and any rider or any team," he said.

"It's a race now that stands on its own two feet, clearly.

"I'm gutted by the revelations that have been made public. I'm disappointed to a level I've never experienced before in cycling."
